- To all whom 'it may'coigcern:

Ile it known that we, Enwaiin F. Inicn. of Lancaster, county ofLancaster. and TBoMAs I". Bexxerr, of Philadelphia, county ofPhiladelphia. State of Pennsyl vania, citizens of the United States,have invented certain new and useful Improvements in IncineratingPlants, of which the followino' is a. specification.

The object of this invention is the construction of a garbage and refusefurnace in which all of the material received is eutirely consumed; inwhich all liquid received is evaporated, and to which there is no needof a sewer connection; in which the. noxious "ases are thoroughlyconsumed; and which icing of simple construction can be installed incommunities Where an expensive plant would be prohibitive; and owing toits snnphcityis of great durability, and when --neeessary to be repairedwill not entail greatI expense.

:The material to be consumed is first subjected to a drying process, andthe extraction of the major portion of its liquids. then drop ed to theniain furnace where it is cxpose for consuming, andthe furtherextract-ion of all liquids and their precipitation to means frovided fortheir complete evaporation. uring the initiai drying i process thereleased gases and vapors are convcdycd to a. heated flue and thereconsume Any heavy sparks or ashes which it would be dangerous `to havepass ont of Fig. 2 is a transverse vertical section on line .c u:Fig. 1. 4 Fig. 3 is a onc-halt` front View. Fig. 4. is an enlargedsectional view showing the corrugated removable separator between thedrying chamber and the inaiu furnace. F f. 5 is a section on line v vFig. 4. Fig. (3

.fla is an enlarged sectional view of a portion of the bridge wall. Fig.7 is au elevation view fof Fig. 6. Fig. 8 is an enlarged sectional view.of the hooded overflow pipes. Fig. 9

is an inverted plan of the hood for the overflow pipes. Fig. 10 is asection on line A Fig. l omitting ash pit Fig. 11 is a .section on linel l5 Fig. 2. i

The structure is incloscd in a back wall 1, side walls :2. one of whichmay be a party wall when a hatten.' of furnaces are constructed, a frontWall 3 for the initial fire box, and an upper front wall Ll. Thestructure includes a chamber as a receptacle for thc material to beconsumed. and in which it is subjected toa dryingr and draining process,comprising a metal ic top part 5, with doors (i through which to dumpthe material into the hopper T, formed of brick at the top of the niainfurnace 8 and supported by an arch 9. rl`he dryingr and draining chamberformed by parts 5. and 'i' is segregated from furnace 8 by an inclinedremovable separator lt), 'which is preferably a heavy metallic platewith corrugat-ions 11, carried on rollers 12 which run on tracks 13 letiu flush into the sides of the brick work. The separator l() is upwardlyinclined toward the outer' sido. of the furnace, and its control forinsertion and withdrawal is by attached racks l-l, operated by pinions15 0n shaft 1G supported iu brackets 1T. Upon shaft4 16 there is agroovcd pulley 18 carrying an endless rope or chain 19 whereb the rackand pinion are operated. iVhee s 20 bear upon the top of the racks tokeep the gear teeth in contact. The separator l0 is stopped, when ,inoperative position so as to leave a space between its inner end 21 andthe adjacent wall, for the flow of liquid. The separator l() being ofmetal becomes intensely heated,

andthe corrugations 11 not onlv greatly in.

crease thc heating surface, and stillen the plate, but form gutters toconvey the liquid to space 21 and project it on to bricks 42, andprojections Stof bricks 33, thereby greatly assisting in the drying outprocess.'

Adjacent the main furnace S, and in communication therewith through arch2:7., is the arched top initial furnace 23 and upon its I,:rates 24 theinitial coal fire is built, an ash pit 25 is under thc grates, andsuitable doors 26, and 27 are provided for the it and tire box. At 2S anopening is provi ed through wall 4 for facilitating the inspeetion ofthe process of incineration. and through which the material may beloosened up for the better aacit of the tlanics from the` initialfurnace ITK. suitable. door will cover the opening Q8 and give accessthereto. The main furnace 8 is provided with a bridge wall :29 forming adowntake tlue 30 between walls l and 2t). The construction of thisbridge wall is illustrated on an enlarged scale in Figs. 6, and where 3lare the apertures formed in diagonal rows by rectangular bricks 3E!forming the sides, and their top and bottom sides formed by theoverlapping dellector bricks 33. Bricks 33 extend into main furnace Sbeyond bricks 32 with their inner ends 34 downwardly curved with a curvebetween bricks 3f! in apertures 31, top part. 35 and the under art 36being upwardly curved, and exten mg between the adjacent'I bricks 3Q,thus, with curves 35 and 36 forming apertures 31 manner to direct, theflames from the pile of refuse lying upon the bars 39 with interstices4G at the bottom ot' main furnace 8,

'downwardly into downtake flue 30.

Owinnr to the multiplicity of diagonally disposedj apertures 31, bothacross and vertically through bridge wall 29 it matters notl how highthe refuse is piled against the bridge Wali 29, as there is sure to be adraft, downwardly tending, into the downtake tine 30. At the upper partof the bridge wall 29 there is a brick 4l which extends into mainfurnace 8 for a less distance than bricks 33, and it has an inwardlysloping top 42, which receives the liquid passing through space 21 andprojects it in toward the center of main furnace 8 and throughinterstices 40 of bars 39 t0 the evaporating table 43 which extendsacross under the Whole bottom partof main furnace 8, and forms the topof the bottom 'lues 44, 45. The evaporating table 43 is provided .withmultiple overflow' pipes 46 which extend somewhat above the' table andare covered with hoods 47 to prevent the passage of any solids, thehoods being removable for cleaning purposes. The overf How pipes aresupported by flanges 48, shaped to afford slig t obstruction to cleanmgtable 43 by Scrapers. Flue 3() has a cover 49, and a side wall 50 overthe flue 45 leading to the stack or chimney and an arch 5i! through itswall into Hue 44. Flue 44 has a concave bottom 53 extending beyonddivision wall 54 which supports table 43 and forms the return flue 45leading to the stack Hue 51, and the lue 45 also has a concave bottom55. A pipe 56 leads from the upper part of part 5 to flue 30 for theconveyance of the fumes and gases released in the drying process.

As seen 1n Fig. 11, iue 5l from its connection t0 Hue 45 is inclinedtoward the stack 57 at its top part 58, and its bottom 59 is level, andtherefrom rises a corbellated back 60, forming a receptacle for thedeposit of any heavy or dangerous articles coming from the furnace, anda cleaning hole 6l facilitates their removal. The necessary cleaningholes are provided as are also the necessary furnace, ash pit and votherdoors, together with the usual binders, stay rods and the other supportsusual 1n such i structures, which are well known and need not. bedescribed. Between 'rates 39 and table 43, through bridge wal 29 thereare openings 62, to form a down draft through intcrsticrs 40 to table 43when the refuse is nearly burned out, for the purpose of consuming anygreasy mass which may lodge on the table.

In the operation of incineration there is tirst a white heat produced inthe initial furnace i223, which has an arched top to deflect the flamesdownwardly into furnace 8, this thoroughly heats main furnace 8, anlseparator 10, then doors 6 are opened and the refuse is dumped intohopper 7 and onto .separator l0, when the released liquids How down inthe gutters of the separator, through spacel. ou to sloping top 42 anddrip on bricks at. 35 and are precipitated through iuterstices 40 totable 43, and the noxious gases and vapors removed through pipe 56 toflue 30. The refuse in hopper 7 having now been dried, sufficiently, andrelieved of its liquids, the separator 10 is run back and the massdumped into main furnace 8 upon bars 39, the mass naturally covering thebals and diminishingr in quantity'as it reaches upward against bridgewall 29. The llames from the initial furnace attack the mass, and, owingt0 the multitudinous apertures 31 the whole mass is reduced to a drystate which renders it fit. to be drawn into initial furnace 23 by rakesintroduced through door 28, where it is utilized as fuel, by theaddition of a. small amount of coal, to consume the following masstojgbe consumed; this completely clestroy'srmferything received, and ata much'decrcased expense thanirf coal had l to be used exclusively.Aperturas 31 owing to the projections 34 covering their' entrance, andtheir curved tops 35 and bottoms 36 direct the hotl flames and airdownward and toward the inner side of wall 1 which becomes veryhot andreadily consumes all that passes thrm'rgh pipe 56, and downwardlytherefrom to arch 52, through ues 44, and 45 on its way to the stack andthoroughly heats thc underside of table 43, meantime the burning mass inmain furnace S heats the top of table 43, so that any liquids passingthrough intcrstices 40 on to the table arc evaporated.

To still further guard againstnon-eva oration of an excess of liquidspassing to ta le 43 an overtiow is prcvided through pi es 46 to concavefloor 53, from which if ll to overflowing the excess will pass to thelowex concave floor 55 of tine 45, and in these concave ioors the liquidis again exposed to the heated air and gases on their way to the stack.By means of openings 62, any fatty adhering sul-stances lodging on table48 4.rc consumei'l, hy the liames from the inicrs't-iccd lioitom l()tlctlectcd to the taille by the. draft. through openings U2 to thedowntala: ilu." l'ln' utilization of refuse with a small prifpor ion ot'coal, in the initial or primat-jt' l'ui nace insults' in ffrcat economy.'lfhc complete evaporation nl all liquids saves the construction ofcounerting sewers, and the burning of the noxious' gases and fatty sul)-stances lrenders this plant void of objections in any locality.
